GRATER.

Application filed July 26, 1924. Serial No. 728,437.

To all whom t may concer/1,:

Be it known that I, FRITZ J. E. PETERS, a citizen of Germany, andresident of Milwaukee, in the county of Milwaukee and State ofVisconsin, have invented certain new and useful Improvements in Graters;and I do hereby declare that lthe following is a full, clear, and enactdescription thereof.

This invention relates to graters.

Qbjects of this invention are to provide a grater which may be attachedto a table top or other suitable support, which may be quickly chargedor filled with the material to be grated, which may be easily operatedto grate the material to the extent desired without soiling the hands ofthe operator and without any danger whatsoever ofabrasion from thegrat-er.

Further objects are to provide a'grater which is so constructed that itmay be readily cleaned, which is adapted to receive any ofV severaldifferent grater plates, and which may be easily and quickly'attachedatany desired point upon asupport.

An embodiment of the invention is shown in the accompanying drawings, inwhich Figure 1 is a vertcial elevation partly in section of the grater.

Figure 2 is a plan view partly in section of the structure shown inFigure 1.

Figure 3 is an enlarged detail of a portion of the grater plate and thesupporting frame.

The grater comprises a standard or body portion 1 which is suitablywebbed and ribbed to provide the requisite strength. This standard isprovided with an upper foot 2 braced from the body portion by means of aweb and is provided with an underhanging body 3 through which a clampingscrew passes, thus adapting the device for attachment to a table 5 orother support.

The body portion 1 is provided with an aperture 6 therethrough which hasslanting side walls 7 for a purpose hereinafter to appear. This bodyportion is further provided adjacent the opening 6 with an outwardlyprojecting bearing lug 8 to which is pivotally attached the rocking bar9, such bar being conveniently held in place by means of the shoulderedmachine screw 10, as shown in Figure 1.

It is to be noted that the bottom portion of the aperture 6 is fiat andis flush with the surface of the extensive bearing or supgrater carryingframe 13.

porting surface for the oscillatory bar or Vlever 9. The outer end ofthis levert)` is provided with a manipulating handle 11 adapted to begrasped by the operator. The inner end of the lever 9 is riveted orotherwise secured to a projecting lug 12 of a This grater carrying frameis provided with an upstanding flange 14 upon which the grater plate 15rests. The grater plate is preferably provided with downturned flanges16 which lit over the flanges 14 of the frame, as Ashown in Figure 3.The lower portion of the Vflanges 16 rest upon the shoulder of the Yframe 14, as shown inFigure 3, and thus a Avery secure support isattained. 4Thebody portion or standard 1 is provided with an overhangingarm 19 which is provided with an elongated sleeve 20 and with anupstanding lug 21. The sleeve 20 slidably receives the elongated arm 22of a U-shaped member,-the shorter arm 23 of such member being pivotallyattached to the upper portion of a follower block 24. A spring 25 isinterposed between the transverse yoke 26 of the U-shaped member and thelug 21 and thus urges the block or follower block 24 downwardly. Theblock 24 is slidably received within a tubular member 27 which isrigidly attached to the outer end of the arm 19, as shown in Figure 1.This tubular member may be of any desired shape, for instancerectangular, as shown in Figure 2, although it is apparent that othershapes may be found advantageous under certain conditions. The upper'end of the tubular member is preferable rounded or beaded to provide afinished appearance, and the lower edges are inturned slightly, asindicated at 28. These lower edges or portions are spaced a slightdistance from the grater plate 15.

In using the device, the pressure block 24 is lifted out of the member27., and the material to be grated is placed within such member.Thereafter the pressure block is repositioned within the tubular member27 and pressesnthe material against the grate-r platel. The operatorthen rocks the lever y9 by means of the handle 1l and thus rapidlygrates the material without any danger vof injuring his hands. Theinturned edges 28 of the tubular member 27 accurately position thematerial to be grated, and in addition to this, form a support for thepressure block 24 when the pressure block is in itsy lowest position,thus preventing such block from contacting with the grater plate 15. Itis to be noted that the rocking bar 9 may have a relatively wide swingdue to the slanting lateral walls 7 of the aperture 6 in the bodyportion, as shown in Figure 2.

It will be seen that a grater has been provided which may be cleaned asthe grater plate 15 may be readily removed by loosening the screws 18,and which is adapted to receive anyone ot a number of different graterplates.

Further, it is to be noted that the device is compact and simple, may becheaply manufactured, and may be readily operated.

Although the invention has been described in considerable detail, it isto be understood that the invention may be variously embodied and is,therefore, to be limited only as claimed.

`I claim:

l. The combination of a supporting standard having` an aperturetherethrough, an oscillatory bar pivoted to said standard and projectingthrough said aperture and having a manipulating handle at its outer end,a grater supporting :trame secured to the inner end of said bar andadapted to be oscillated thereby, said frame having upstanding flanges,a grater plate adapted to rest upon said flanges and having downturnedHanges adapted to fit thereover, means for temporarily locking saidgrater plate to said frame, a tubular member rigidly carried by saidstandard above said grater plate7 and adapted to receive material to begrated therein, and a spring urged pressure block located within saidtubular ymember and adapted to press such material into contact withsaid grater plate.

2. The combination of a supporting standard having an aperturetherethrough, an oscillatory bar pivoted to said standard and projectingthrough said aperture and having a manipulating handle at its outer end,a grater supporting frame secured to the inner end of said bar andadaptedy to be oscillated thereby, said Jrame having upstanding flanges,a grater plate adapted to rest upon said tlanges and having downturnedflanges adapted to lit thereover, means for temporarily locking saidgrater plate to said frame, a tubular member rigidly carried by saidstandard above said grater plate, and adapted to receive material to begrated therein, and a spring urged pressure block located within saidtubular member and adapted to press such material into contact with saidgrater plate, said tubular member having int-urned lower edges adaptedto prevent the passage osaid pressure block downwardly into contact withsaid grater plate.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee, in the county or" Milwaukee and State of Wisconsin.
